Clonorchis sinensis is one of the trematode species that parasitize humans. Other parasitic trematode species of humans are Paragonimus westermani and Fasciola hepatica. These three species are classified as tissue flukes to separate them from the blood flukes, e.g. Schistosoma spp. Clonorchis sinensis is a tissue fluke that infests the liver of its definitive host. It is endemic in Japan, Taiwan, China, and Southeast Asia. Hence, it is commonly referred to as oriental liver fluke.
